Abstract
A 65-year-old woman with no history of previous flank trauma, renal stone or upper urinary tract infections, presented for flank pain and left hydro-uretero-nephrosis seven days after hysterectomy. Percutaneous pielography revealed narowing of the distal ureter, without endoureteral mass. The plain abdomen film incidentally showed a 3-cm calcified ring on the left renal shadow, who resulted external to the collecting system at pielography. A 3-dimensional-CT scan with angiographic reconstruction revealed a 3-cm calcified renal artery aneurysm. The vascular surgeon suggested a watchful waiting. The patient underwent ureteral reimplantation with ureteral stenting, allowing a complete recovery of iatrogenic stenosis two months postoperatively.
Highlights
Renal artery aneurysms have been encountered with increasing frequency over the past decade
We incidentally discovered a lesion of the left renal artery and we completed the diagnostic work-up with a 3D-CT scan
Renal artery aneurysms (RAA) are rare, with an estimated incidence below 1%
Summary
Renal artery aneurysms have been encountered with increasing frequency over the past decade. It is slightly more common in women than men and in the right than left renal artery [1]. Angiography is the gold standard in the diagnosis of renovascular injuries, and it has the additional advantage to possesses the potential of therapeutic intervention [2]. After any invasive urological procedure, CT angiography can be considered as the first choice for renal artery injury [3,4]. We incidentally discovered a lesion of the left renal artery and we completed the diagnostic work-up with a 3D-CT scan
